Tom on one side and George Harper on the other, they managed to haul Ollie out, but the sudden drop had jarred him to the point of nausea and for several yards, as they double-quicked it to catch up with their line, they virtually carried their chum along, each of them holding to one of his arms.

Looking skyward Tom made another discovery. It was as though great flocks of giant birds peopled the air. Aeroplanes of every capacity and description and in various formations were maneuvering over their heads and beyond them.

Watching them as he trotted along, Tom saw from time to time a smaller scout plane separate itself from its group and dart forward and out of sight over the enemy lines. Presently it would return, sometimes to remain with its squadron, at others to continue back to some signalling point in the rear, from which it relayed the facts of the German’s position or movements.

Massive battle and bombing planes plowed along, their powerful motors beating a tremendous bass throb as their big propellers churned the air.

Here and there, too, were anchored observation baloons, the observers in them, equipped with parachutes for a long jump to safety at any time, sitting at telephone instruments connected with the various headquarters.

On the land and in the sky the battle was on—the history-making battle of the St. Mihiel salient!

Once a German aero battle fleet that a few months before would have been considered the most formidable fighting unit that ever took the air, sailed forward as if to engage the American gunners and pilots in a struggle; but either their courage failed them or better judgment prevailed, for there was a quick signal from the leader of the group, and with greater speed than they had approached they turned and fled toward their own lines.

“Fritz isn’t feeling very well this morning,” the irrepressible “Buck” Granger shouted, and a merry shout arose from the men who were within hearing of the remark.

And, indeed, it seemed to be the truth. Fritz was getting some of his own medicine, and apparently he considered it a rather bitter dose.

The smoke ahead began to dissipate itself in the brisk early morning breeze, and the men had their first realization that the firing behind them had almost ceased.
